Title: Driving wheel differential joint employing hydraulic pressure
Inventor: MATSUURA TETSUO
IPC: F16H48/20
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To obtain excellent differential characteristics by a simple structure by providing two coaxial gears while being spaced by a partition plate, letting each small gear be meshed with the aforesaid gears respectively, and letting the respective gears be functioned as a hydraulic pump/a hydraulic motor in filled-up oil. SOLUTION: Driving force from a large bevel gear 4 causes small gears 3A and 3B over the satellite orbits of coaxial gears 2A and 2B to be rotated over their orbits through a main body 1A. In this case, if loadings of two pairs of gears which are meshed with each other while being spaced by a partition plate 6 are identical, hydraulic pressures generated are mutually canceled, and the main body 1A is thereby integrally rotated together with the gears 2A and 2B, and the small gears 3A and 3B. Meanwhile, if the gear 2A at one side is stopped through the driving wheel, the small gear 3A itsself is rotated over its orbit, so that hydraulic pressure is thereby generated. The aforesaid pressure is acted on the gear 2B and the small gear 3B so as to allow these to be functioned as a gear motor, and thereby the gear 2B is rotated at the increased speed.  Besides, since oil flow is obstructed by a valve within the partition plate, differential torque can thereby be restrained.

Title: Vehicle slip control device
Inventor: YAMASHITA TETSUHIRO
IPC: B60K28/16
Filed: 1991-11-06
Abstract: PURPOSE:To enhance the acceleration property of a vehicle equipped with a limited slip differential not only when the vehicle travels on a normal road surface but also when the vehicle travels on a split road surface using a slip control unit provided in the vehicle to perform traction control (engine control). CONSTITUTION:At the step S3, split judgement processing is executed to see whether or not a vehicle travels on a split road surface according to the spin patterns of right and left driving wheels. If the vehicle does not travel on a split road surface (split control flag FS is not set) at the step S4, normal control is executed at the step S5. If the vehicle travels on a split road surface, the control shifts to the step 6, at which split control is executed(traction control whereby a target control value is corrected by increasing it more than during normal control so that driving wheel slippage is permitted). Thereby limiting of engine output more than required due to the slip of one of the driving wheels is prevented and the acceleration property of the vehicle is held at its maximum by the other driving wheel having sufficient gripping forces against the road surface.

Abstract: PURPOSE:To obtain a number of printed matters speedily by using a printing master plate with an insulative pattern layer of a corresponding positive or reversed negative image to image symbol information formed on a heat-conducting base with a conductive layer on the surface layer part. CONSTITUTION:The heat-conducting base of an electrostatic printing maser plate has a conductive layer on the surface layer part. The heat conductivity allows a heat signal to reach the other surface of the base when said signal is transmitted from one surface of the base. A laminated body consisting of resin or paper film and a conductive layer, a metallic plate foil and a conductivity-treated paper are used as the base. In addition, the conductive layer has conductivity and is made of a material with a specific resistance of less than 10<10>OMEGA.cm. Gold, silver and copper or their alloys and oxide alloys are used for the conductive layer. An insulative pattern layer of a corresponding positive or reversed negative image to image symbol information is formed on the surface of the conductive layer. Consequently, when this printing master plate is charged, the insulative pattern layer surface of the positive or negative image is charged. However, the conductive layer surface is not charged because it is electrically conductive. Therefore, a plurality of printed matters can easily be obtained speedily.
